We can bypass using the VersionContext in the feature flag API by passing-in a dummy kVersionContextIgnored value. This will make the feature-flag check rely on the node's local FCV only. Since this can potentially lead to inconsistent behaviour, this approach should be used with a lot of care.

The goal of this ticket is the add a rule to the linter to make sure that every usage of kVersionContextIgnored is accompanied by a comment explaining the reasoning behind that choice.
